Detailed Description

The advantages, features, and methods of attaining the above-described advantages and features of the invention will become apparent from the following detailed description of illustrative embodiments of the invention when considered in conjunction with the accompanying drawings. However, the present invention can be realized in various forms, and is not limited to the embodiments disclosed below, but the present invention is provided only for completely disclosing the present invention and completely informing a person of ordinary skill in the art to which the present invention belongs of the scope of the present invention, and the present invention is defined only according to the scope of the claims. Throughout the specification, the same reference numerals denote the same constituent elements.

Fig. 1a shows an outer shield shell 10-1 (outer shield shell), an inner shield shell 10-2 (inner shield shell), an RF signal terminal 10-3, a signal terminal 10-4, and a housing 10-5 (molded part) of the plug connector 10.

The RF signal terminal 10-3 is a terminal for transmitting and receiving a high frequency signal (for example, a frequency signal of about 50 GHz). The signal terminal 10-4 is a terminal that transmits and receives a signal of a relatively lower frequency than the RF signal terminal 10-3. The signal terminal 10-4 may be the following terminal: the frequency range that was processed in the existing connector before the connector corresponding to 5G is processed. The use in 5G wireless communication is an example, but not necessarily limited thereto. A current at the level of the power supply terminal may also be passed to the signal terminal 10-4 as desired. As an example, the signal terminal 10-4 may include 6 PINs (PINs) that allow a current of 0.3A, and may be a terminal that allows a current exceeding 0.3A to, for example, 5A to function as a power supply terminal. Of these, 6 PINs are an example.

The outer shield case 10-1 serves to shield the RF signal terminal 10-3 that transmits and receives high-frequency signals. The inner shield case 10-2 also functions to shield the RF signal terminal 10-3 for transmitting and receiving high-frequency signals.

The housing 10-5 has a base portion. The housing 10-5 has a wall portion protruding from the upper surface of the base portion, and the wall portion is formed with an RF signal terminal 10-3, an inner shield case 10-2, a signal terminal 10-4, and the like.

The housing 10-5 (molded portion) of the plug connector 10 is preferably a plastic material, and may be, for example, Liquid Crystal Polymer (LCP). In addition, the housing 10-5 may be formed of an insulator including a resin, an epoxy resin, and the like, but is not limited thereto. The RF signal terminals 10-3 and the signal terminals 10-4 of the plug connector 10 are preferably made of a metal material, such as copper, or a material obtained by plating a copper alloy with gold (nickel plating), but not limited thereto.

The outer shield case 10-1 and the inner shield case 10-2 may be made of a material for shielding electromagnetic waves, for example, a metal such as aluminum, a polymer composite material, a material obtained by coating or spraying a metal on a plastic, a carbon material such as graphene, or the like, or may be made of a material similar to or the same as the RF signal terminal 10-3 and the signal terminal 10-4.

The shielding structure is as follows: the "outer shield shell 10-1 and the inner shield shell 10-2 of the plug connector 10" surround the "RF signal terminals 10-3 of the plug connector 10" and the "RF signal terminals 20-3 of the receptacle connector 20" in cooperation with the "outer shield shell 20-1 and the inner shield shell 20-2 of the receptacle connector 20" described below, thereby performing shielding.

The portion that presents the largest area when viewed from the bottom is the outer shield 10-1. A signal terminal 10-4 is disposed in the middle portion of the plug connector 10.

The inner shield shell 10-2 is disposed on the outer side (the outer side in the longitudinal direction (X direction) of the plug connector 10) of the signal terminal 10-4. In the longitudinal direction (X direction) of the plug connector 10, an RF signal terminal 10-3 is present between the outer shield shell 10-1 and the inner shield shell 10-2.

The receptacle connector 20 is also referred to as a receptacle connector 20.

In fig. 2a, the outer shield 20-1, the inner shield 20-2, the RF signal terminals 20-3, the signal terminals 20-4, and the housing 20-5 (mold) of the receptacle connector 20 are shown.

The RF signal terminal 20-3 is a terminal for transmitting and receiving a high frequency signal. The signal terminal 20-4 is a terminal that transmits and receives a signal of a relatively lower frequency than the RF signal terminal 20-3. It is also possible to flow a current of a power supply terminal level to the signal terminal 20-4 as necessary.

The outer shield 20-1 serves to shield the RF signal terminal 20-3 for transmitting and receiving high-frequency signals. The inner shield 20-2 also functions to shield the RF signal terminal 20-3 for transmitting and receiving high-frequency signals.

The housing 20-5 (molded part) of the receptacle connector 20 is preferably made of a plastic material, such as LCP (liquid Crystal Polymer). The RF signal terminals 20-3 and the signal terminals 20-4 of the receptacle connector 20 are preferably made of a metal material, for example, a copper alloy plated with gold (nickel base). The outer shield 20-1 and the inner shield 20-2 may be made of a material for shielding electromagnetic waves, for example, a metal such as aluminum, a polymer composite material, a material obtained by coating or spraying a metal on a plastic, a carbon material such as graphene, or the like, or may be made of a material similar to or the same as the RF signal terminal 20-3 and the signal terminal 20-4.

The shielding structure is as follows: the "outer shield shell 10-1 and inner shield shell 10-2" of the plug connector 10 "surround the" RF signal terminal 10-3 "of the plug connector 10" and the "RF signal terminal 20-3" of the receptacle connector 20 "in cooperation with the" outer shield shell 20-1 and inner shield shell 20-2 "of the receptacle connector 20" to shield the RF signal terminals.

The portion that presents the largest area when viewed from the bottom is the outer shield 20-1. The signal terminals 20-4 are arranged in the middle portion of the receptacle connector 20.

The inner shield shell 20-2 is disposed on the outer side (the outer side in the longitudinal direction (X direction) of the receptacle connector 20) of the signal terminal 20-4. In the longitudinal direction (X direction) of the receptacle connector 20, there is an RF signal terminal 20-3 between the outer shield shell 20-1 and the inner shield shell 20-2.

Fig. 3 is a further enlarged view of the plug connector 10 of fig. 1a, 1 b.

Fig. 3 (a) is a view showing the plug connector 10 shown in fig. 1a at another angle. The housing 10-5 is preferably a piece of plastic rather than a plastic assembly, and the outer shield 10-1 is preferably a piece of metal rather than a metal assembly, but not limited thereto.

Fig. 3 (b) is a view showing a case where the outer shield case 10-1 and the housing 10-5 are removed from fig. 3 (a). It can be confirmed that the RF signal terminal 10-3 is disposed on the outermost side in the longitudinal direction (X direction) of the plug connector 10, the inner shield case 10-2 is disposed inside the RF signal terminal, and the signal terminal 10-4 is disposed inside the RF signal terminal.

Fig. 4 is a further enlarged view of the receptacle connector 20 of fig. 2a and 2 b.

Fig. 4 (a) is a view showing the receptacle connector 20 shown in fig. 2a at another angle. The housing 20-5 is preferably a piece of plastic rather than a plastic assembly, and the outer shield 20-1 is preferably a piece of metal rather than a metal assembly, but is not so limited.

Fig. 4 (b) is a view showing a case where the outer shield 20-1 and the housing 20-5 are removed from fig. 4 (a). It is confirmed that the RF signal terminals 20-3 are arranged on the outermost side in the longitudinal direction (X direction) of the receptacle connector 20, the inner shield 20-2 is arranged inside the RF signal terminals, and the signal terminals 20-4 are arranged inside the RF signal terminals. Although the inner shield 20-2 is described as being disposed inside the RF signal terminal 20-3 (in the X direction), it is also possible to overlap a part of the range in the X direction, as is apparent from the figure.

Fig. 5 shows a cross section along line AA in a state where the plug connector 10 of fig. 1a, 3 is turned upside down and fastened to the receptacle connector 20 of fig. 2a, 4.

Fig. 5 shows a case where the outer shield shell 10-1 of the plug connector 10 is coupled to the outer shield shell 20-1 of the receptacle connector 20, and a case where the RF signal terminal 10-3 of the plug connector 10 is coupled to the RF signal terminal 20-3 of the receptacle connector 20.

When the cross section (i.e., YZ plane) of fig. 5 is viewed, the combination of the outer shield case 10-1 and the outer shield case 20-1 has a shape in which the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3 is covered in the Y direction (width direction of the connectors 10 and 20).

For reference, the outer shield shell 10-1 is elastically deformed when it is coupled with the outer shield shell 20-1, but such elastic deformation is omitted in fig. 5 and only the coupling is conceptually shown. Similarly, the RF signal terminal 10-3 is elastically deformed when it is coupled to the RF signal terminal 20-3, but such elastic deformation is omitted in fig. 5 and only the mutual coupling is conceptually shown. Therefore, a part of the positions where elastic deformation is required is shown as overlapping.

Fig. 6 shows a cross section taken along the line BB in a state where the plug connector 10 of fig. 1a and 3 is turned upside down and fastened to the receptacle connector 20 of fig. 2a and 4.

Fig. 6 shows a case where the outer shield shell 10-1 of the plug connector 10 is coupled to the outer shield shell 20-1 of the receptacle connector 20, and a case where the signal terminal 10-4 of the plug connector 10 is coupled to the signal terminal 20-4 of the receptacle connector 20.

When the cross section (i.e., YZ plane) of fig. 6 is viewed, the combination of the outer shield case 10-1 and the outer shield case 20-1 has a shape in which the combination of the signal terminal 10-4 and the signal terminal 20-4 is covered in the Y direction (width direction of the connectors 10 and 20).

For reference, the outer shield shell 10-1 is elastically deformed when it is coupled with the outer shield shell 20-1, but such elastic deformation is omitted in fig. 6 and only the coupling is conceptually shown. Similarly, the elastic deformation occurs when the signal terminal 10-4 is coupled with the signal terminal 20-4, but such elastic deformation is omitted in fig. 6 and only the coupling is conceptually shown. Therefore, a part of the positions where elastic deformation is required is shown as overlapping.

Fig. 7 is a bottom view of the plug connector 10 of fig. 1a and 3 with the shell 10-5 removed.

If the outer case 10-5 is not provided, the inner shield case 10-2, the RF signal terminal 10-3, and the signal terminal 10-4 cannot be located at the home position, but fig. 7 is a view assuming that the outer case 10-5 is removed and the remaining components are located at the home position. At this time, the coupling between the components (particularly, the coupling with the opposing connector, i.e., the receptacle connector 20) can be confirmed more easily.

If the outer case 20-5 is not present, the inner shield 20-2, the RF signal terminals 20-3, and the signal terminals 20-4 cannot be located at the home position, but fig. 8 is a view assuming that the outer case 20-5 is removed and the remaining components are located at the home position. At this time, the coupling between the components (particularly, the coupling with the opposing connector, i.e., the plug connector 10) can be confirmed more easily.

Fig. 9 shows a state in which the plug connector 10 and the receptacle connector 20 are fastened in a state in which the housings 10-5, 20-5 are removed, similarly to fig. 7 and 8. In fig. 9, the plug connector 10 is located in the + Z direction and the receptacle connector 20 is located in the-Z direction.

As can be seen from fig. 9, the RF signal terminals 10-3 of the plug connector 10 and the RF signal terminals 20-3 of the receptacle connector 20 are coupled (fastened) to each other. Also, the inner shield case 10-2 and the inner shield case 20-2 are coupled to each other, and the outer shield case 10-1 and the outer shield case 20-1 are coupled to each other.

Further, it is understood that the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" is located between the "combination of the outer shield case 10-1 and the outer shield case 20-1" and the "combination of the inner shield case 10-2 and the inner shield case 20-2" in the longitudinal direction (X direction) of the

connectors

10 and 20.

In addition, it is understood that "the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" is located between "the combination of the outer shield case 10-1 and the outer shield case 20-1" in the width direction (Y direction) of the

connectors

10 and 20. It is also understood that at least a part of the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" is located between the "combination of the inner shield case 10-2 and the inner shield case 20-2" in the width direction (Y direction) of the

connectors

10 and 20.

According to this structure, the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" can be electrically shielded (electromagnetic wave shielding) by the "combination of the outer shield case 10-1 and the outer shield case 20-1" and the "combination of the inner shield case 10-2 and the inner shield case 20-2".

Fig. 10 is a view showing a CC section of fig. 9.

As can be seen from the CC section of fig. 10, the outer shield shell 10-1 (plug outer shield shell) of the plug connector 10 is brought into contact with the outer shield shell 20-1 (jack outer shield shell) of the receptacle connector 20 and the inner shield shell 20-2 (jack inner shield shell) of the receptacle connector 20 by the insertion (fitting) fastening. Thus, the components 20-1, 10-1, 20-2 are electrically connected. And, the inside shield shell 20-2 of the receptacle connector also comes into contact with the inside shield shell 10-1 of the plug connector. However, as shown in fig. 10, 7, etc., there is no contact between the inside ends 10-2IE of the inside shield shells 10-2 of the plug connectors.

For example, one of the main components for well shielding the RF signal terminals 10-3, 20-3 is a structure in which the outer shield shell 10-1 of the plug connector electrically connects the outer shield shell 20-1 of the receptacle connector and the inner shield shell 20-2 of the receptacle connector like a bridge.

The outer shields 10-1, 20-1 and the inner shields 10-2, 20-2 are coupled to surround the RF signal terminals 10-3, 20-3 in the longitudinal direction and the width direction of the

connectors

10, 20 as a whole.

In the example shown in the drawings, the outer shield shell 10-1 of the plug connector electrically connects the outer shield shell 20-1 of the receptacle connector and the inner shield shell 20-2 of the receptacle connector, but as an example, the outer shield shell of the electrical connector may be electrically connected to the outer shield shell and the inner shield shell of the connector opposite to each other. If the electrical connector is a plug connector 10, the opposite connector is a receptacle connector 20, and conversely, if the electrical connector is a receptacle connector 20, the opposite connector is a plug connector 10.

In addition, in the example of the drawings, the outer shield shell 10-1 of the plug connector is one piece, and the outer shield shell 20-1 of the receptacle connector is also one piece. However, the outer shield shell 10-1 or 20-1 like a bridge may be arranged so as to cover 4 surfaces of the

connector

10 or 20, or may be one piece like the drawing, or may be a plurality of pieces (for example, two pieces).

As shown in fig. 7 and 9, the inner shield shell 10-2 is present between the RF signal terminal 10-3 and the signal terminal 10-4 in the longitudinal direction (X direction) of the plug connector 10. Of course, there may be a slight overlap in the longitudinal direction if necessary. The RF signal terminals 10-3 and 20-3 are better covered by the overlapping, and therefore the electromagnetic wave shielding effect is large.

As shown in fig. 8 and 9, the inner shield shell 20-2 is present between the RF signal terminal 20-3 and the signal terminal 20-4 in the longitudinal direction (X direction) of the receptacle connector 20. Of course, as shown in the figure, there may be a slightly overlapping section in the longitudinal direction (for example, the RF signal terminal 20-3 overlaps with a partial section of the inner shield 20-2 in the longitudinal direction (X direction)).

In other words, the inner shields 10-2, 20-2 may be disposed on both sides in the longitudinal direction (X direction) of the signal terminals 10-4, 20-4.

On the other hand, FIG. 10 shows mounting parts 10-1M, 10-2MI, 10-2MO, 20-1M, 20-2MO, and 20-2 MI. The mounting portions are portions for mounting (e.g., soldering, etc.) the respective components 10-1, 10-2 of the plug connector 10 to a substrate, and are portions for mounting the respective components 20-1, 20-2 of the receptacle connector 20 to a substrate (another substrate).

Specifically, the outer shield shell 10-1 (a first outer shield shell, as an example) has a mounting portion 10-1M for a substrate below the plug connector 10 (an example, an electric connector) in the height direction (the direction-Z in fig. 3 and 7, and the direction + Z in fig. 10 in which the plug connector 10 is turned upside down and joined), and has a bent portion extending from the mounting portion 10-1M to above the plug connector 10 (an example, an electric connector) in the height direction (the direction + Z in fig. 3 and 7, and the direction-Z in fig. 10 in which the plug connector 10 is turned upside down and joined), and when the plug connector 10 (an example, an electric connector) is inserted into the receptacle connector 20 (an example, an opposing connector), at least a part of the bent portion and the receptacle connector 20 (for example, opposing connectors) to contact at least a portion of the outer shield 20-1.

As described above, if the plug connector is referred to as an electrical connector, the receptacle connector is an opposite connector. Of course, without being limited thereto, if the receptacle connector is referred to as an electrical connector, the plug connector is an opposite connector.

In addition, the inner shield shell 10-2 (e.g., the first inner shield shell) of the plug connector 10 has a mounting portion 10-2MO (e.g., a first mounting portion) for a substrate below the height direction of the plug connector 10 (e.g., an electrical connector) (in fig. 3 and 7, the direction is the-Z direction, and in fig. 10, the direction is the + Z direction, where the plug connector 10 is turned upside down and joined), has a bent portion extending from the mounting portion 10-2MO to above the height direction of the plug connector (e.g., the electrical connector) (in fig. 3 and 7, the direction is the-Z direction, in fig. 10, where the plug connector 10 is turned upside down and joined), and has a mounting portion for a substrate extending from the bent portion again to below the height direction of the plug connector 10 (e.g., the electrical connector) (in fig. 3 and 7, the direction is the + Z direction, in fig. 10, where the plug connector 10 is turned upside down and joined) Section 10-2MI (e.g., second mounting section).

Here too, as described above, if the plug connector is referred to as an electrical connector, the receptacle connector is an opposing connector. Of course, without being limited thereto, if the receptacle connector is referred to as an electrical connector, the plug connector is an opposite connector.

Fig. 11 is a view showing an AA section in fig. 4 (a).

In the receptacle connector 20, the height of the uppermost end of the inner shield shell 20-2 is higher than the height of the uppermost end of the RF signal terminal 20-3. The height direction is the Z direction in fig. 11, the upper side in the height direction is the + Z direction, and the lower side in the height direction is the-Z direction.

According to this structure, even if an external force (pressing force) is applied when the plug connector 10 is coupled to the receptacle connector 20, most of the force is received by the inner shield shell 20-2, and the pressing force is not transmitted to the RF signal terminals 20-3, thereby preventing the RF signal terminals 20-3 from being damaged.

That is, the inner shield 20-2 not only functions to shield electromagnetic waves from the RF signal terminal 20-3, but also protects the RF signal terminal 20-3 from physical forces.

Fig. 11 illustrates only the receptacle connector 20, but as can be seen from fig. 3, the height of the uppermost end of the inner shield shell 10-2 is also higher than the height of the uppermost end of the RF signal terminal 10-3 in the plug connector. The height direction is shown as the Z direction in fig. 4, the upper side of the height direction is the + Z direction, and the lower side of the height direction is the-Z direction.

According to this structure, even if an external force (pressing force) is applied when the plug connector 10 is coupled to the receptacle connector 20, most of the force is received by the inner shield case 10-2, and the pressing force is not transmitted to the RF signal terminals 10-3, thereby preventing the RF signal terminals 10-3 from being damaged.

That is, the inner shield case 10-2 not only functions to shield electromagnetic waves from the RF signal terminal 10-3, but also protects the RF signal terminal 10-3 from physical forces.

More specifically, the combination of the inner shield case 10-2 and the inner shield case 20-2 not only functions to shield electromagnetic waves from the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3, but also protects the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3 from physical forces.

There are shown 3 holes 10-H1, 10-H2, 10-H3, which are structures for impedance matching, as explained in detail in fig. 13 and 14.

Fig. 14 is also a view showing a state of being inserted with the plug connector 10 positioned downward (-Z direction) and the receptacle connector 20 positioned upward (+ Z direction), in which the viewing direction is slightly different from fig. 13.

First, the first hole 10-H1 is as follows: in the width direction (Y direction) of the plug connector 10, a portion of the housing 10-5 between two contact points formed by the RF signal terminals 10-3 of the plug connector 10 being in contact with the RF signal terminals 20-3 of the receptacle connector 20 is formed. The first hole 10-H1 is used to achieve impedance matching.

In addition, the second hole 10-H2 and the third hole 10-H3 are the following holes: in the fitting direction (height direction, Z direction) of the plug connector 10 and the receptacle connector 20, portions of the housing 10-5 are formed below two contact points formed by the RF signal terminals 10-3 of the plug connector 10 and the RF signal terminals 20-3 of the receptacle connector 20 being in contact, respectively. The holes 10-H2, 10-H3 are also used to achieve impedance matching.

For example, when a signal of about 50GHz is transmitted and received through the RF signal terminals 10-3 and 20-3, if the holes 10-H1, 10-H2 and 10-H3 are not provided, reflection loss occurs when a signal source and a circuit of a load are connected. By appropriately selecting the positions of these holes to reduce the reflection loss, it is possible to improve the sensitivity of the component during operation (for example, to improve the signal-to-noise ratio, the linearity of the frequency characteristic, and the like).

The positions of the second holes 10 to H2 and the third holes 10 to H3 shown in FIG. 14 are preferable examples, but the present invention is not necessarily limited thereto. Since the preferred position is a position for reducing the reflection loss, the impedance can be appropriately changed to match the impedance according to the state of each element. For example, in FIG. 14, only the second aperture 10-H2 may be present and the third aperture 10-H3 may not be present. Alternatively, in FIG. 14, only the third holes 10-H3 may be present and the second holes 10-H2 may not be present. In addition, although only one side in the longitudinal direction of the connector is shown in fig. 13 and 14, as shown in fig. 1a and the like, the RF signal terminal 10-3 is present on one side in the longitudinal direction of the plug connector 10 (for example, the-X direction, the left side in fig. 1 a), and the other RF signal terminal 10-3 is present on the other side in the longitudinal direction of the plug connector 10 (for example, the + X direction, the right side in fig. 1 a), only one hole (one of the second hole and the third hole) may be present in the housing 10-5 on the bottom surface near the RF signal terminal 10-3 on the left side, and two holes may be present in the housing 10-5 on the bottom surface near the RF signal terminal 10-3 on the right side. Conversely, only one hole (one of the second hole and the third hole) may be present in the bottom surface of the housing 10-5 near the RF signal terminal 10-3 on the right side, and two holes may be present in the bottom surface of the housing 10-5 near the RF signal terminal 10-3 on the left side. There may be only one hole (one of the second hole and the third hole) in the case 10-5 of the bottom surface near the RF signal terminal 10-3 on the left side, and there may be only one hole (one of the second hole and the third hole) in the case 10-5 of the bottom surface near the RF signal terminal 10-3 on the right side. In this case, the holes may be disposed to face each other in point symmetry with reference to the center of the plug connector 10, or may be disposed to face each other in point symmetry with reference to the center line in the longitudinal direction or the width direction. Such a configuration may be any combination that enables impedance matching. In the typical example shown in fig. 13 and 14, the second hole 10-H2 and the third hole 10-H3 are also present in the bottom case 10-5 near the left RF signal terminal 10-3 (of fig. 1 a), and the second hole 10-H2 and the third hole 10-H3 are also present in the bottom case 10-5 near the right RF signal terminal 10-3.

Referring to the coupling state of fig. 13 and 14, or the state in which the receptacle connector 20 of fig. 4 is alone, the inner shield shell 20-2 covers at least a part of the RF signal terminals 20-3 on both sides in the width direction (Y direction) of the receptacle connector 20. This not only serves to shield the electromagnetic waves from the RF signal terminals 20-3 and 10-3, but also serves to prevent physical damage to the RF signal terminals 20-3 and 10-3.

In general, this can be described as follows: the inner shield 10-2 or 20-2 covers at least a part of the outer side of the RF signal terminal 10-3 or 20-3 on both sides in the width direction of the

electrical connector

10 or 20. Of course, in fig. 4 of the embodiment, the RF signal terminals 20-3 of the receptacle connector 20 are surrounded by the inner shield shell 20-2 in the width direction, and in fig. 3, the RF signal terminals 10-3 of the plug connector 10 are not surrounded by the inner shield shell 10-2 in the width direction, but this is merely an example.

That is, in contrast to fig. 3 and 4, the following configuration may be adopted: the RF signal terminals 20-3 of the receptacle connector 20 are not surrounded by the inner shield shell 20-2 in the width direction, and the RF signal terminals 10-3 of the plug connector 10 are surrounded by the inner shield shell 10-2 in the width direction. Alternatively, the following forms are also possible: the RF signal terminals 20-3 of the receptacle connector 20 are surrounded by the inner shield shell 20-2 in the width direction, and the RF signal terminals 10-3 of the plug connector 10 are also surrounded by the inner shield shell 10-2 in the width direction.

The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited to the embodiments and can be manufactured in other various forms, and a person having ordinary skill in the art to which the present invention belongs will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features of the present invention. It is therefore to be understood that the above described embodiments are illustrative in all respects and not restrictive.
